Asbestos
The material at this site contains levels of naturally-occurring asbestos (NOA) that resulted in the site being closed in 2003. In 2012, the State of Alaska Legislature enacted House Bill 258, which provided users immunity against claims arising from the use of NOA gravel.

 

In addition to NANA gravel request requirements, the State of Alaska Department of Transportation & Public Facilities (ADOT&PF) regulates the use of NOA material. Therefore, ADOT&PF should be contacted before planning to use NOA gravel. 

 

For more information about NOA Gravel regulations, please contact the ADOT&PF or visit the NOA Program web page.
